SPECIFICATION forming part of LettersV Patent o. 711,787, dated October21, 1902. Application iiled February 5,1902. Serial No.I 92,643. (Nomodel.)

To all whom, it may concern:

Be it known that I, FREDERICK RABINNO- vITZ, a citizen of the UnitedStates, and a resident of Fort Totten, in the county of Benson and Stateof North Dakota, have invented a new and Improved Tabulator, of whichthe following is a full, clear, and exact description.

This invention relates particularly to improvements in devices designedto be attached to type-writing machines, linotype-machines,

and others similarly operated (and where the` word type-writer ishereinafter used other machines similarly operated are to beunderstood)for convenience in tabulating; and the object is to provide a device ofthis character that shall be simple in construction, having no partsliable to get out of order,`and that may be quickly operated to indicatethe proper places to stop the machine-carriage when writing figures orother tabulated matter or to indicate particular places wanted foroperation or omission in the work.

I will describe a tabulator embodying my invention and then point outthe `novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indi catecorresponding parts in all the figures.

Figure 1 is a plan view of a tabulator embodying my invention. Fig. 2 isa front view thereof with a portion of the casing broken away and withparts in section. Fig. 3 is an end view; and Figs. 4 and 5 are sections,respectively, on the lines 4 4 and 5 5 of Fig. 1.

This tabulator is designed to be attached to the front portion of atype-writer or typewriter carriage, as the construction of thetype-writing machine may require, and it comprises a casing 11, whichpreferably will extend the entire length of the scale-plate and issecured to` the type-writer or carriage, as the case may require.Extending through the casing is a shaft 12, which has its bearings inthe end walls of the casing, as clearly shown in the drawings. On thefront of the casing 11 is a scale 13, corresponding to the scale on thefront plate of the type-writer. This casing in its front wall isprovided with an opening or, preferably, with a series of slots oropenings 14, in which indexes 15 are designed to move. Each index 15 isextended from a disk-like body portion`16, mounted to rotate on theshaft 12, and the several indicatingdevices are spaced and held apart bymeans of washers 17. These several washers are connected, through themedium of arms 18, with a bar 19, extended through the casing, and fromthis bar 19 a stem 20 extends outward-through an opening 21 in a holdingdevice for the indexes, consisting,"as here shown, of a.transversely-curvedV plate 22,y having swinging connection with the rearedge of the casing 1l. The free end of this plate 22 is designed toengage in either one ot' the notches 23 or 24 in the disk-like bodyportion of an index, and the plate is held yieldinglyin engagement withthe parts by means of a spring 25, surrounding thestem 20 andengaging atone end with the plate and at the other end with an adjusting-nut 26 onthe threaded portion of the stem. It may be here stated that while onestem 2O will answer every purpose to hold the plate in yieldingengagement with the indexes two or more of such stems may be employed,if desired, and it vis also to be vunderstood that the severalwashersneed not be connected one with another; but I prefer this construction,as any possible lateral movement of the indicating devices is thusprevented. p

The normal position of the several indexes is substantially Vertical orin a rearward position, as indicated in Fig. 5. In use, however, as manyas desired of the indexes are to be moved downward, as indicated in Fig.2, to indicate the particular places on the scale to be taken cognizanceof. These indexes will be moved down upon the scale 13 at the pointscorresponding to the scale on they IOO accidental movement. When in theopposite position, however, the plate will engage in notch 23.

It will be noted that the shaft 12 is located forward of thecasing-axis, so that when the indexes are swung back or in normalposition they will have but a slight projection through the slots of thecasing, and therefore are not liable to catch into a persons clothing`or the like.

For convenience in relieving an index or indexes from pressure whenmoving from or returning the same to normal position, the plate 22 maybe sprung out of engagement therewith. For this purpose I extend a pinor lever 27 from one end of the plate through an opening in an end wallof the casing or some convenient place in the'casing itself.

This device may not only be used in tabulating or forming columns offigures, but it may be found convenient in addressing envelops and, infact, in all matter where the beginning and ending of lines are designedto be in straight vertical rows and in all cases where the position ofletters or figures must be gaged to be held within given limitations.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. A tabulator for a type-writer, comprising a casingadapted to be secured to the typewriter carriage, a shaft extendedthrough the casing, a series ofiudexes mounted to swing on said shaft,the said casing being provided with openings to receive the indexes anda yielding holding device common to all the indexes, substantially asspecified.

2. A tabulator attachment for a type-writer, comprising a casing, ashaft extended lengthwise through the casing and forward of its axis,the said casing being provided with slots in its front wall, a series ofindexes mounted to swing on said shaft and extended through the slots,and spacing devices between the indexes, substantially as specified.

3. Atabulatorattachmentforatype-Writer, comprising a casing having slotsin its front wall, a shaft extended longitudinally through the casingand forward of its axis, a series of indexes extended through the slotsand having body portions mounted to swing on the shaft, spacing-washersarranged between the body portions, and a connection between the severalspacing washers, substantially as specified.

4. A tabulating attachment for a typewriter, comprising a casing havingopenings in its front wall, a shaft extended longitudinally through thecasing, a series of indexes mounted to swing on the shaft and extendedthrough the openings, and means for yieldingly holding the indexes ineither 'adj usted position, substantially as specified.

5. A tabulating attachment for a typewriter, comprising a casing havingopenings in its front Wall, a shaft extended longitudinally through thecasing, a series of indexes mounted to swing on said shaft and movablein said openings, spacing-washers arranged between the indexes on theshaft, a bar connection between the several washers, a plate havingswinging connection with the casing, and means for holding the plate inyielding connection with the indexes, substantially as specified. y t

6. A tabulating attachment for a typewriter, comprising a casing havingopenings in its front wall, a shaft extended longitudinally through thecasing, a series of indexes having plate-like body portions mounted toswing on the shaft, the said indexes being extended through theopenings, the said body portions being provided with notches,spacing-washers on the shaft between the body portions, a bar connectionbetween the several spacing-washers, a plate having swinging connectionwith the casing and adapted to engage in the notches of the said bodyportions, a stem extended outward from the bar connecting the washers,through an opening in said plate, an adjusting-nut on said stem, andaspring arranged between the adjustingnut and said plate, substantiallyas specified.

7. A tabulating attachment for a typewriter, comprising a casinghavingopenings in its front wall, a shaft extended longitudinally through thecasing, a series of indexes having plate-like body portions mounted toswing on the shaft, the said indexes being extended through theopenings, the said body portions being provided with notches,spacing-washers on the shaft between the body portions, a bar connectionbetween the several spacing-washers, a plate having swinging connectionwith the casing, and adapted to engage in the notches of the said bodyportions, a stem extended outward from the bar connecting the washersthrough an opening in said plate, an adjusting-nut on said stein, aspring arranged between the ad justing-nut and said plate, and a pin, orlever, extended outward from one end of the plate, through an opening inone of the walls of the casing, substantially as speciiied.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
